Crystal bought b boxes of cookies to bring to a party. each box contains 18 cookies. she decides to keep two boxes for herself. she brings 90 cookies to the party. which equation can be used to find the number of b boxes crystal bought?
a) 2b − 18 = 90
b) 18b − 2 = 90
c) 18b − 36 = 90
d) 36 − 18b = 90

fyi it aint b

Step-by-step explanation:

idk tho lol

the answer is B

Hope this helps

(a)the slope of the secant line on the interval [1,3] represents the average velocity of the object  over that interval.the definition of average velocity is    where  is the displacement of the object over that time interval.(b)the slope of the tangent line at the point t = 2 represents the instantaneous velocity of the object at t = 2 (2 hours after the start time).  if the object had a speedometer, and you snapped a picture of it at t = 2 hours, then that would be the instantaneous  velocity of that object.(c)a linear function has parts (a) and (b) equal. graphically, a linear function is a straight line.a linear function has a constant slope, a constant rate of change. the tangent line slope would be the same as the secant line slope.
